40. Isolated torsion of the fallopian
tube
 Rare cause of lower quadrant pain primarily affecting
adolescents and ovulating women. Risk factors:PID,
tubal ligation, neoplasm, adhesions, gravid uterus and
trauma.
 Complications include fallopian tube necrosis, an
increased risk for superinfection and peritonitis. Local
necrosis can also result in irreversible damage to the
ipsilateral ovary.
 Treatment options include surgical detorsion,
salpingotomy, and salpingectomy depending on the stage
of intervention and presence of complications.

•Uncommon syndrome (2-3%)of delayed white
matter injury after a hypoxic-ischemic injury, most
commonly due to carbon monoxide intoxication
•Period of relative clinical stability or
improvement, then acute neurologic decline,
typically 2-3 weeks after the initial insult
•DWI and conventional MRI immediately
following the insult may be normal, but reveal
confluent areas of restricted diffusion in the
cerebral white matter later
•Imaging helps in diagnosis and case
management in the acute setting and provides
information about long term prognosis

130. Case1:84 M with RLQ pain for 3 days
Linear foreign bodyExtraluminal air
Fat stranding

131. Dx: Small bowel perforation due to a chicken bone
Take home points-
1. Evaluate the perivisceral/mesenteric fat. Dirty fat is an
indicator of acute inflammation
2. Play with the window settings on your PACS

132. Small bowel perforation by a foreign
body
 Fewer than 1% ingested foreign bodies (usually sharp and
elongated) result in intestinal perforation
 Small bowel is the most common site, particularly areas of
acute angulation
 Susceptible population-people wearing dentures, children,
alcoholics, psychiatric patients
 Signs and symptoms: abdominal pain, nausea, vomiting,
fever, peritonitis, abscess, fistula, small bowel obstruction
and GI hemorrhage
 CT can detect type of foreign bodies-bone, metal and wood;
localize the site of FB impaction and detect perforation
 Treatment: surgical exploration and repair

133. Don’t trust cows that write !

134. Case 2: 56 M with abdominal pain
Disrupted bowel wall
and focal thickening
Foreign body

135. Dx: Impacted tooth with small bowel perforation
Take home points-
1. Look for any discrepancy in bowel morphology.
2. Discontinuity in mucosal enhancement may indicate
perforation, in absence of free air.
3. Careful review can give an idea of the nature of foreign body

136. Case 3: SBO due to an ingested earring

137. Case 4: 40 F with colicky abdominal pain
High grade small bowel obstruction with small
bowel feces sign in the pelvis.
Retained endoscopic capsule at the point of
obstruction and underlying bowel stricture due
to Crohn’s disease
Active inflammatory bowel disease (Crohn's
disease) with multiple long segments of bowel wall
thickening, strictures and creeping fat sign.

138. Endoscopic capsule as a cause of small bowel obstruction in
a case of Crohn's disease
Take home points-
1. Look for the small bowel feces sign to identify the point of
obstruction
2. Careful review can give an idea of the nature of foreign body
3. Look for a possible underlying stricture at the site of foreign
body

139. Case 5: 64 M with abdominal pain and vomiting

140. Dx: Cholecystogastric fistula with gastric outlet obstruction

141. Gastric outlet obstruction caused by a large gallstone
passing into the duodenal bulb through a biliogastric or
bilioduodenal fistula.
What is it called?
Bouveret's syndrome

142. Extraluminal fecal matter in the peritoneal cavity and air loculi
Fecaloma at
the perforation
site
Colon wall thickening due to pressure necrosis
Case 6: 67 F with constipation x 5 d, abdominal
pain and distension

143. Dx: Stercoral perforation

144. Stercoral colitis
 Fecal impaction may rarely lead to perforation, colonic obstruction
and fecal peritonitis.
 Fecal impaction results in ischemic pressure necrosis of the rectal
and sigmoid colonic wall leading to stercoral ulcer formation and
subsequently perforation.
 Most common locations :anterior rectum, the antimesenteric border
of the rectosigmoid junction, and the sigmoid colon.
 Mean age 59 yrs. Risk factors : chronic intermittent constipation,
use of nonsteroidal anti-inflammatory drugs, antacids, steroids,
codeine, and heroin.
 Presence of underlying diverticulitis, IBD or obstruction excludes
the diagnosis of primary stercoral perforation.

145. Does it stink in your ER?

146. Case 7: 38 M with acute onset severe abdominal pain

147. Cecum in the lesser sac
Cecum mildly dilatedCecum in the lesser sac between
the liver hilum and IVC
No twist to indicate cecal volvulus
Case 7: 38 M with acute onset severe abdominal pain

148. Dx: Lesser sac hernia with cecal incarceration
Take home points-
1. Look for abnormal location of a bowel loop indicating an internal
hernia
2. Abnormal dilatation of the abnormally located loop may indicate
incarceration
3. Absence of beak sign or mesenteric twist can exclude volvulus

149. Lesser sac hernia via the foramen of
Winslow
Review of Internal Hernias: Radiographic and Clinical Findings. LC Martin et
al. AJR March 2006
Lesser sac hernias comprise 8% of all
internal hernias which have a less than 1%

151. Active hemorrhage from a branch of the right gastric artery

152. Dx:Mesenteric vasculitis with active hemorrhage
Take home points-
1. Sentinel clot sign
2. Recognize the appearance of
extraluminal contrast indicative of
active hemorrhage.
3. Vessel morphology to detect the
cause for bleed

153. Bilateral large adnexal
masses with hyperdense
components.
Right
ovary
Left ovary
Free fluid
Uterine deviation to the right
Case 9: 25 F with RLQ pain
Soft tissue deposit

154. Dx: Bilateral struma ovarii with torsion of
the right ovary and benign strumosis
Take home points-
1. Consider the possibility of torsion in presence of a large adnexal
mass and appropriate clinical setting
2. Ascites , abnormal location of the ovary, ipsilateral deviation of the
uterus indicate adnexal torsion

155. Struma ovarii
 Struma ovarii is composed predominantly of thyroid
tissue. It accounts for approximately 3% of all mature
cystic teratomas
 US and CT demonstrate its complex appearance
with multiple cystic and solid areas. When struma
ovarii is not associated with hyperthyroidism, the
differential diagnosis should include mature cystic
teratoma without fatty tissue, cystadenoma or
cystadenocarcinoma, endometriosis, tuboovarian
abscess, and metastatic tumor
 Malignant transformation of thyroid tissue in struma
ovarii and metastasis are extremely uncommon
 In rare cases, benign thyroid tissue may spread to
the peritoneal cavity. This condition is termed
"peritoneal strumosis."

156. Case 10: 20 F with LLQ pain
Whirl sign: spiral appearance
of the vascular pedicle
Periadnexal fat
infiltration
Uterus (U)deviated to the
left

Right ovarian teratoma
Left ovarian teratoma

157. Dx: Bilateral ovarian dermoid cysts with
torsion on the left
Take home point-
Look for the whirl sign in adnexal torsion

158. Case 11: 12 cm cystic tumor of the right ovary. Is
there torsion?
No wall thickening, fat infiltration,
ascites or ipsilateral uterine
deviation
Left

thickening

160. Case 15: 25 year old pregnant female with RLQ
pain. Free fluid seen on the sonogram. Fetal
cardiac activity absent.
Hemoperitoneum
Fetal parts
Uterus defect

161. Dx: Ruptured uterine pregnancy
 Uterine rupture in pregnancy is a rare (0.07%)and
catastrophic complication with high incidence of fetal
and maternal morbidity.
 Signs and symptoms nonspecific resulting in a delayed
diagnosis.
 Unlike uterine scar dehiscence, uterine rupture is a full-
thickness separation of the uterine wall and overlying
serosa. Associated with massive bleeding, fetal
distress and expulsion or protrusion of fetus, placenta
or both into the abdominal cavity.
 Risk factors:Scarred uterus, placenta accreta/percreta,
multiple gestation, molar pregnancy, obstructed labor

162. Case 16: 57 M with a stiff neck and sore throat
CT findings:
Elongated irregular calcification
anterior to the C1 vertebra extending
up to mid C2 level.
Ill-defined fluid in the prevertebral
space extending from C1 through C4-5
level without rim enhancement.
No other evidence of inflammatory
changes.

163. Dx: Acute calcific tendinitis of the longus colli
 Aka acute prevertebral calcific tendinitis and
retropharyngeal calcific tendinitis
 Relatively benign and unusual cause of acute neck
pain and stiffness. Inflammatory process caused by
calcium hydroxyapatite crystal deposition in the
superior oblique tendon of the longus colli muscles
 Clinically mimics more serious entities such as
retropharyngeal abscess, spondylodiscitis or spine
trauma
 Recognition of calcific tendinitis of the longus colli is
important to prevent unnecessary intervention

164. Case 18: MVA,chest pain
Dx: Buckle fractures of the
sternum

165. Case 21: 23 F with leukocytosis, RLQ pain and tenderness,
vaginal discharge, cervical motion tenderness
Arterial phase
nephrourographic phase

166. Dx: TOA with perihepatitis (Fitz-Hugh Curtis Syndrome)
 Characterized by right sided abdominal
pain and perihepatitis associated with
pelvic inflammatory disease (gonococcal
or chlamydial)
 Localized RUQ peritonitis (hepatic
capsular/pericapsular enhancement on
the arterial phase) with PID (mild pelvic
edema, thickened fallopian tubes,
enlarged ovary, abnormal endometrial
enhancement and fluid, frank
tuboovarian abscess) suggest the
diagnosis
